EVOLUTION OF THE MASS AND LUMINOSITY FUNCTIONS OF GLOBULAR STAR CLUSTERS [PDF]

open access: yesThe Astrophysical Journal, 2016
ABSTRACT We reexamine the dynamical evolution of the mass and luminosity functions of globular star clusters (GCMF and GCLF). Fall & Zhang (2001, FZ01) showed that a power-law MF, as commonly seen among young cluster systems, would evolve by dynamical processes over a Hubble time into a peaked MF with a shape very similar to the ...

The luminosity function of young star clusters: implications for the maximum mass and luminosity of clusters [PDF]

open access: yesAstronomy & Astrophysics, 2006
We introduce a method to relate a possible truncation of the star cluster mass function at the high mass end to the shape of the cluster luminosity function (LF). We compare the observed LFs of five galaxies containing young star clusters with synthetic cluster population models with varying initial conditions.

The luminosity and mass functions of the Pleiades: low-mass stars and brown dwarfs [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1991
COSMOS measurements of R and I Schmidt plates are used to determine the luminosity function and hence mass function of the Pleiades open cluster. Star counts are made in the cluster and the field star contribution, measured outside the cluster, is subtracted. The mass function is found down to 0.06 m ○. .

The Gaia DR2 halo white dwarf population: the luminosity function, mass distribution, and its star formation history [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2021
ABSTRACT We analyse the volume-limited nearly complete 100 pc sample of 95 halo white dwarf candidates identified by the second data release of Gaia. Based on a detailed population synthesis model, we apply a method that relies on Gaia astrometry and photometry to accurately derive the individual white dwarf parameters.

On the determination of age and mass functions of stars in young open star clusters from the analysis of their luminosity functions [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2004
Based on the CCD observations of remote young open clusters NGC 2383, NGC 2384, NGC 4103, NGC 4755, NGC 7510 and Hogg 15, we constructed their observed luminosity functions (LFs). The observed LFs are corrected for field star contamination determined with the help of galactic star count model.
